Chapter 1 - Introduction
ASUS SL1200
1 Introduction
Thank you for buying the ASUS SL1200, the Internet Security Router!
Your Local Area Network (LAN) will now be able to access the Internet
using high-speed broadband connection such as those with ADSL or cable
modem.
This user manual will show you how to set up the ASUS SL1200, and how
to customize its conguration to get the most out of this product.
1.1 Features
• 10/100Base-T Ethernet router to provide Internet connectivity to all
computers on your LAN
• Firewall, NAT (Network Address Translation), and IPSec VPN
functions to provide secure Internet access for your LAN
• Automatic network address assignment through DHCP Server
• Services including IP route, DNS and DDNS conguration, RIP, and IP
performance monitoring
• Conguration program accessible via a web browser, such as
Microsoft Internet Explorer 5.5, Netscape 7.0.2 or later.
1.2 System Requirements
In order to use the ASUS SL1200 for Internet access, you must have the
following:
• ADSL or cable modem and the corresponding service up and running,
with at least one public Internet address assigned to your WAN
• One or more computers each containing an Ethernet 10Base-
T/100Base-T network interface card (NIC)
• (Optional) An Ethernet hub/switch, if you are connecting the device to
more than four computers on an Ethernet network.
